MMS2

Bits 20-23: Master mode selection 2.

Allowed values:

1: Enable: Enable - the Counter Enable signal CNT_EN is used as trigger output (TRGO2). It is useful to start several timers at the same time or to control a window in which a slave timer is enabled. The Counter Enable signal is generated by a logic AND between the CEN control bit and the trigger input when configured in Gated mode. When the Counter Enable signal is controlled by the trigger input, there is a delay on TRGO2, except if the Master/Slave mode is selected (see the MSM bit description in TIMx_SMCR register)
2: Update: Update - the update event is selected as trigger output (TRGO2). For instance, a master timer can then be used as a prescaler for a slave timer
3: ComparePulse: Compare pulse - the trigger output sends a positive pulse when the CC1IF flag is to be set (even if it was already high), as soon as a capture or compare match occurs (TRGO2)
4: CompareOC1: Compare - OC1REFC signal is used as trigger output (TRGO2)

SMS

Bits 0-2: Slave mode selection.

Allowed values:
0: DisabledOrCombined: Slave mode disabled - if CEN = ‘1 then the prescaler is clocked directly by the internal clock. If SMS[3]=1 then Combined reset + trigger mode - Rising edge of the selected trigger input (TRGI) reinitializes the counter, generates an update of the registers and starts the counter
1: EncoderMode1: Encoder mode 1 - Counter counts up/down on TI2FP1 edge depending on TI1FP2 level
2: EncoderMode2: Encoder mode 2 - Counter counts up/down on TI1FP2 edge depending on TI2FP1 level
3: EncoderMode3: Encoder mode 3 - Counter counts up/down on both TI1FP1 and TI2FP2 edges depending on the level of the other input
4: ResetMode: Reset Mode - Rising edge of the selected trigger input (TRGI) reinitializes the counter and generates an update of the registers
